Title: Alignment detector
Inventor: IWAZAWA TOSHIYUKI
IPC: H01L21/30
Filed: 1991-08-09
Abstract: PURPOSE:To detect an alignment with high reliability and accuracy by eliminating instability of a vibration mirror due to extraneous vibration, concerning an alignment detector to be used in a reduction projection aligner or other device. CONSTITUTION:Let the repetition rate of an excimer laser oscillator 1 be Fa, and the frequency at which the orignal pattern can be reproduced when sampling is carried out at Fa be f (f is smaller than 1/10 of Fa). A vibration mirror 13 is driven at the frequency Fm=Fa+f or Fm=Fa-f. A differential frequency signal generator 22 and a phase shifter 23 are installed, and a signal whose frequency is the difference between Fa and Fm (¦Fa-Fm¦) is generated by the differential frequency signal generator 22. The phase of the signal is shifted by the phase shifter 23 so that the signal may be synchronous with an output signal of a low-pass filter 27. After that, the phase-shifted frequency signal is inputted into a phase detector 28. By this method, an alignment detector with high reliability and accuracy can be provided.

Title: Vibration proof device for camera
Inventor: SHIOMI YASUHIKO
IPC: G03B5/00
Filed: 1990-07-31
Abstract: PURPOSE:To improve minimum resolution for controlled vibration by analogically obtaining the output of difference between the displacement amount of blurring with respect to absolute space and the displacement amount of the inclination of a correction optical means, digitally calculating the output of the difference and obtaining output for control of the correction optical means. CONSTITUTION:A floating body 4 which can be freely rotated is disposed in liquid 3 filling up an outer jacket 2. Signal light from a light emitting element 6 is reflected on the surface of the floating body 4 and made incident on a light receiving element for detecting a position 5. Then, it is changed by a current outputted by the element 5 and the movement of the floating body 4 when the body 4 is relatively rotated with respect to the jacket 2. On the other hand, the displacement amount of the angle of a variable apex angle prism 41 which is used as the correction optical means is also detected by the same method as a blurring detection means. Then, the difference between the displacement output of the blurring of the blurring detection means and the output of the displacement of the angle of the prism 41, that means, the output of the difference between the displacement amount of the blurring with respect to the absolute space and the displacement amount of the inclination of the correction optical means is analogically obtained. Thereafter, the output of the difference is digitally calculated and the output for control of the correction optical means is obtained. Thus, the minimum resolution for controlled the vibration is improved.

Title: D-a conversion circuit
Inventor: ASAZAWA HIROSHI
IPC: H03M1/78
Filed: 1988-08-12
Abstract: PURPOSE:To form a power supply for a D/A converter including an operational amplifier with a single power supply by applying a voltage VAG calculated by a special relation equation with respect to the design center value VM of an output voltage to a noninverting input of the operational amplifier in the D/A converter using the operational amplifier. CONSTITUTION:A noninverting input of an operational amplifier 1 is connected to an analog ground having a voltage VAG expressed as VAG=(2RMIN+.VM+ RF.VREF/2RMIN+RF), where VREF is a reference voltage, RF is a feedback resistor, RMIN is a minimum value of a variable resistor, and VM is a design center value of an output voltage. For example, the minimum value of the variable resistor is selected to be RF and the center value of the output voltage is selected to be VREF/2. The relation of VAG=2RF.VREF/3RF=2VREF 13 is obtained by substituting VM=FREF/2 and RMIN=RF to the equation above. Then the analog ground voltage VAG is easily obtained by applying 2VREF/3 (by the division of the voltage VREF by three resistors) to the noninverting input of the operational amplifier.

IPC: G01C15/06
Filed: 1987-08-14
Abstract: PURPOSE:To obtain a level rod whose scale is highly precise in regard to a change in temperature and whose quality is uniform, by using a scale plate and a frame having positive and negative coefficients of linear expansion respectively and by correcting elastic deformation equivalent to a difference in thermal expansion between them. CONSTITUTION:A scale tape plate 1 having a negative coefficient of expansion and having a scale 5 provided on the surface is disposed inside a metal frame 2 having a positive coefficient of expansion, and the lower end of the plate is fixed, together with the frame 2, to a bottom cover 3. The upper end thereof is connected to an elastic member (coil spring) 8 whose one end is made to engage with the inside of the frame 2 in a top cover 4, and thereby a tension is given to the tape plate 1. The elastic constant of this member 8 is set at a numerical value for correcting elastic deformation equivalent to a difference in thermal expansion between the tape plate 1 and the frame 2. Accordingly, an elastic force of the member 8 is varied to act so that it offsets the expansion and contraction of the tape plate 1 caused by a change in temperature, and thus the precision of the scale of the tape plate 1 is maintained irrespective of the change in temperature.

Title: Device for transmitting driving force
Inventor: YAMAMOTO MASAJI
IPC: F16D43/284
Filed: 1988-08-15
Abstract: PURPOSE:To improve the durability of a clutch in the driving-force transmission of a four-wheel-drive vehicle by recessedly providing a sub-chamber in a cylinder housing opposite to a space portion, partitioning the sub-chamber from the space with a partition board, and housing a high-viscous fluid also in this sub- chamber. CONSTITUTION:A space portion 43 in which a high-viscous fluid is sealed is provided on the side of an operating piston 36. A sub-chamber 50 is recessedly provided on a cylinder housing 32 opposite to this space portion 43. The portion between this sub-chamber 50 and the space portion 43 is partitioned by a partition board 51 on which connecting holes 52 are provided. The high-viscous fluid is also housed in the sub-chamber 50. Since the sealing quantity of the high-viscous fluid is increased by the amount of the capacity of the sub-chamber 50 increasing the expanding quantity of the high-viscous fluid due to temperature rise, a transmission torque can be greatly increased with respect to temperature rise. Thereby, the durability of a clutch can be improved.

Abstract: PURPOSE:To diagnose an abnormal phenomenon accurately by correcting a monitoring threshold value, which is to be decided on the basis of a reference spectrum, on the basis of rotational synchronous frequency of a rotor at the time when a diagnostic objective spectrum is obtained. CONSTITUTION:A reference spectrum storage means 1 stores multiple reference spectrums, and a diagnostic objective spectrum analyzing means 2 analyzes the measuring signal from a vibration detector fitted to a rotary equipment to obtain diagnostic objective spectrum. A reference spectrum selecting means 3 selects the reference spectrum, which is formed under the operation condition nearest to the diagnostic objective spectrum, among the reference spectrums stored in the reference spectrum storage means 1. A monitoring threshold value to be decided on the basis of the selected reference spectrum is corrected by a threshold value correcting means 4 on the basis of the rotational synchronous frequency of a rotor at the time when the diagnostic objective spectrum is obtained. A monitor means 5 uses the pilot threshold value after the correction to monitor abnormal phenomenon to be generated in the rotary equipment.
